Graphene Oxide–Based Nanomaterials: An Insight into Retinal Prosthesis

Functionalized graphene nanomaterials: new insight into direct exfoliation of graphite with supramolecular polymers.

A novel urea-cytosine end-capped polypropylene glycol (UrCy-PPG) can self-assemble into a long-range ordered lamellar microstructure on the surface of graphene, due to the strong specific interactions between UrCy-PPG and graphene. In addition, the graphene composite produced exhibits a high conductivity (∼1093 S m(-1)) with a dramatic thermo-responsive ON/OFF resistance-switching behavior (10 ...

Physicochemical insight into gap openings in graphene

Based on a newly developed size-dependent cohesive energy formula for two-dimensional materials, a unified theoretical model was established to illustrate the gap openings in disordered graphene flakes, involving quantum dots, nanoribbons and nanoporous sheets. It tells us that the openings are essentially dominated by the variation in cohesive energy of C atoms, associated to the edge physicoc...

Preparation of Nanocomposite Heteropoly Metalate Based Graphene Oxide: Insight into Cadmium Adsorption

We developed a facile strategy for preparation of heteropoly metalate/graphene oxide nanocomposite as a new ion exchanger for cadmium ion removal from aqueous solution. The synthesized nanocomposite was characterized by X-ray powder diffraction (XRD), UV-Vis spectroscopy, FT-IR spectroscopy and Raman spectroscopy. Our findings indicated that the combination of heteropoly metalate nanoparticles ...

Nanomaterials: Graphene rests easy.

699 news & views etching of large sheets represents an attractive alternative because it is able to achieve uniform, organized arrays 7. Unfortunately, the complexity of the tools necessary for sub-10-nm patterning and an inability to control edge roughness represent significant limitations to this technique. Sprinkle, de Heer and colleagues report progress towards a very different approach, in...
